The cows are my neighbor's and I've been building my fence steadily for the last months. I build only with materials I can get from the forest and use mainly old fashioned non-powered tools (except for the phone and a drill which are solar powered) because I love this planet and don't support the oil fueled culture we live in.
As you can imagine, this is a lot of work and time, so it's not because I think it's ok to leave the garden in care of cows, it's just there is much to do yet.
